Love the main enemy design you had going on for the spiked baddie. Also, the player movement and level design felt fairly snappy and good! Reminds me of Quake lol
If I could give some quick feedback, when it comes to the art, I was kind of hoping to see more of that design you had for the spiked guy in the rest of the game. Would've been cool if maybe you limited the color palette to only purples, or even captured some of that sinister alien-like sharp and pointy design in the "shooting enemy" and the weapons/environment.
Either way, if y'all keep working on this, keep it up!
